Big Bubble

Big Bubbles,[1] also known as Bubbles[2] or Green Bubbles,[3] as their name implies, are huge green bubbles that appear in Super Mario World. They only appear in the Ghost Houses and if jumped on or touched, Mario or Luigi will be hurt, with the exception of using a Spin Jump, or Slope Slide which actually destroys them. They are very big and can block Mario or Luigi's path.
